I've seen these floating around the internet on blogs.
The "window" consists of attributes you give to yourself and your friends give you. There are the ones you choose for yourself, the ones your friends choose for you. The ones Both you and your friends choose.
And the ones neither your nor your friends choose.
There are too differen sets of windows, the Johari which is the good attributes adn the Nohari which is the bad.
You can choose MY attributes at the following links, and get a better idea of what I'm talking about. Prehaps to create your own?
(note, I used an alternate name than the one I usually use, but it is me)
My Good Attributes (Johari Window )
My Bad Attributes (Nohari Win dow)
